Hey congratulations! I hope you enjoy owning a printer!
I had a very similar experience building my first printer (a Prusa MK3S) a bit over five years ago. I’ve rebuilt it a couple of times since.
That experience is serving me well as I build a Voron 2.4R2 (with ASA parts printed on the MK3S). The learning curve part appears to be largely behind me, and owning the Prusa did help ease that since they make a lot of things pretty easy.
Plenty use it without knowing as it is what the Steam Deck uses in gaming mode.
